Lavender plant named ‘Belrou’

ABSTRACT

A new and distinct cultivar of Lavender plant named ‘Belrou’, characterized by its upright, somewhat outwardly spreading and mounded plant habit; freely branching habit, dense and bushy plant form; vigorous growth habit; and violet-colored flowers with light pink-colored terminal flower bracts.

Botanical designation: Lavandula stoechas.

Cultivar denomination: ‘Belrou’.

CROSS-REFERENCE TO RELATED APPLICATIONS

The present application is co-pending with the following related application: U.S. Plant patent application Ser. No. 11/113,372, Lavender Plant Named ‘Belros’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Lavender plant, botanically known as Lavandula stoechas, and hereinafter referred to by the name ‘Belrou’.

The new Lavender is a product of a planned breeding program conducted by the Inventor in Kulnura, New South Wales, Australia. The objective of the breeding program was to create new compact and freely branching Lavender cultivars with large and attractive flowers and good garden performance.

The new Lavender originated from an open-pollination in 1999 of a proprietary selection of Lavandula stoechas identified as code number 00-38, not patented, as the female, or seed, parent with an unknown selection of Lavandula stoechas, as the male, or pollen, parent. The new Lavender was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated open-pollination grown in a controlled environment in Kulnura, New South Wales, Australia in September, 2000.

Asexual reproduction of the new cultivar by terminal cuttings at Kulnura, New South Wales, Australia, since 2000, has shown that the unique features of this new Lavender are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar ‘Belrou’ have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Belrou’. These characteristics in combination distinguish ‘Belrou’ as a new and distinct cultivar:

-   -   1. Upright, somewhat outwardly spreading and mounded plant         habit.     -   2. Freely branching habit, dense and bushy plant form.     -   3. Vigorous growth habit.     -   4. Violet-colored flowers with light pink-colored terminal         flower bracts.

Plants of the new Lavender differ from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Lavender and the female parent selection         differ in flower coloration.     -   2. Plants of the new Lavender and the female parent selection         differ in flower bract coloration.

Plants of the new Lavender differ primarily from plants of the cultivar ‘Belros’, disclosed in U.S. Plant patent application Ser. No. 11/113,372, in flower and terminal flower bract coloration.

Plants of the new Lavender can be compared to plants of the Lavender cultivar Kew Red, not patented. In side-by-side comparisons conducted in Kulnura, New South Wales, Australia, plants of the new Lavender differed from plants of the cultivar Kew Red in the following characteristics:

-   -   1. Plants of the new Lavender were taller and more uniform in         growth habit than plants of the cultivar Kew Red.     -   2. Plants of the new Lavender had longer leaves than plants of         the cultivar Kew Red.     -   3. Plants of the new Lavender had larger terminal flower bracts         than plants of the cultivar Kew Red.     -   4. Plants of the new Lavender and the cultivar Kew Red differed         in terminal flower bract coloration as plants of the cultivar         Kew Red had light lavender-colored terminal flower bracts.     -   5. Plants of the new Lavender had longer peduncles than plants         of the cultivar Kew Red.
